I have one Paypal account and it's setup for my current store (let's call it STORE A). I have a new store coming out and I know I can setup specific pages for the checkout of that store with Paypal's page styles so that's not an issue.
An issue however is... since IPN already points to my current store's IPN script, how can I get that data to my other store based on what store's email address they are paying?
I don't think Paypal supports multiple IPN addresses so I was thinking I could hack the STORE A's IPN script to check the email address that received the money and if it's STORE B, it can send that data over to STORE B's IPN script (kind of like a pass-through).
Is this a good idea? Anyone with specific code samples?
